I've got a pair of DENON SC-C3 from my uncle. It is two ways speaker use 1 woofer and 1 tweeter per cabinet.
I've dismantled the parts to see inside and founded that the tweeters was wired in phase on one and the other was out of phase from the factory.They use 2nd order passive crossover network. So now I can't remember the left or the right tweeter was wired out of phase or mayby I could be mistaken that actually both of Left and right was wired out of phase from the factory . I was very confused
.
I need some help. Please give me suggestions about the wiring of tweeters what should I connect them ? Should I wiring them both out of phase ? or only one cabinet out of phase and if wiring only side It should be Left or Right side.
Thank you.

No, both speakers should be (from my point of view) the same, unless they were not symmetrical (exception).
Phase then (or not), it's the final adjustment in relation of the speakers (drivers) and xover (xover/order) and xover frequency.😉
(You can test both). Describe or post a picture of xover.

the wiring diagram which I knew.
red ==> + woofer
black ==> - woofer
orange ==> ? tweeter
white ==> ? tweeter

black ==> - woofer
orange ==> ? tweeter
white ==> ? tweeter
If the photos you show are the entire crossover, than unless there are some components hidden from view, that is a first order 6dB crossover. One inductor for the woofer and one capacitor fro the tweeter. The woofer and the tweeter should be wired in-phase for both speaker cabinets.
A 2-way speaker using a 2nd order 12dB crossover has the tweeter wired out-of-phase.
Edit: It is difficult to tell from the photos, are those components indeed only connected to the tweeter? Are you sure the inductor is not in series with the woofer and the cap in series with the tweeter?

probably best with reversed phase on tweeter
but depends
if your xo is made to work without reversed phase, things might get more complicated
note that the reversed connection can be done either at xo, or at tweeter
I'm sure you must be missing some attenuation on tweeter

In that case I would wire woofer and the tweeter in-phase. Since there is no crossover on the woofer, there is no phase shift. The tweeter crossover does cause phase shift but the woofer and tweeter will not be 180 degrees out of phase. I built a set of 2-way, 1st order on the woofer, 2nd order on the tweeter, and wired them in-phase.
If the woofer exhibits an acoustic crossover, it also exhibits the phase change associated with the acoustic crossover.
Does it roll off by itself at 6, 12, 18 dB per octave, or something in between ?
Phase shift is not dictated only by the capacitors and inductors.
Passive crossovers with a single capacitor and inductor can end up being closer to 18 or 24 dB per octave than 12.
Without testing the speaker the chances are about 50/50 of getting the correct polarity using "conventional wisdom".
Without test gear, I'd call the factory rather than guessing.

Or without test gear or a phone call you could connect them both ways and see which one you like.
Yes, you can. The wrong polarity will cause a dip somewhere in the crossover region.
Many people listening to the wrong polarity will prefer the scooped out mid sound of the dip, just as DJs seem to like the "smiley face " eq.
The polar response will shift up or down or left or right in the crossover region depending on woofer and tweeter orientation, and room location, further complicating the choice- what sounds good in one listening position may sound bad in others.
All this A/B comparison can provide endless hours of fun😛.

+1 try both and see which one you like. In any event, if it's a stereo pair of speakers, the tweeter wiring should be the same for both.
Email Denon and ask them? I doubt they'd have a problem in answering your question. Just say the speakers sounded odd and you noticed that one had the tweeter wired up with reverse polarity vs the other and that you want to know the correct way to wire them up.
